RULING DEVICE.

T c all whom it may concern:

Be it known that I, EIHVARD A. Amm- ISAC-11', a-citizen of the United States, residing in New .York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Ruling Devices, of which the following is a specification.

This invention has for its object t9 ,broduce an improved device for ruling or making section lines on paper or other objects. in which the supporting arm is removably attached to a ruler to slide along the same, and is provided with adjustable means earrying markers that can be set at various distances apart to form parallel lines when the supporting arm is slid along the ruler.

In the accompanying drawing representing an embodiment of my invention, Figure 1 shows the device in use. Fig. 2 shows the supporting arm in elevation. Fig. 3 is an elevation enlarged of one of the markers.

Fig. 4c is a plan view of the latter. Fig. 5- is an end elevation of the same. Fig. 6

shows in elevation; and Fig. 7 in plan the socket member for holding two markers in close proximity.

The device comprises essentially a sup porting arm for attachment to a ruler, and

a plurality or series of markers adj ustably' carried thereby. The support is shown as comprising a block 6 having a flange T bent downward and then at right angles parallel with the main portion for engagement with rabbeted edge 8 of a rule 9. The support has an adjustable member formed by an angle piece 10 having-a slot 11 through which a screw 12 is passed that screws into the support portion (3. The angle piece is shown as extending into a. channel 13 in the top of the ruler. This angle piece together with the flange portion 7 serves to retain the support on the ruler, and the screw member el amps the angle piece so that the block will have a tree sliding movement along the ruler, yet prevent any lateral movement or play.

A plurality of marking devices are provided, which are adjustable along the slotted arm to be clamped in various posit-ions thereto. Each otthese is shown as comprising a block 20 having a tongue 21 extending downwardly and fitting the slot 15 snugly to slide therein. A set screw 22- is tapped into the tongue, and will engage the lower face of the slotted arm, to clamp the Specification of Letters Patent.

block 20 in adjusted positions along the arm. This block has an arm carried thereby to press a marker against the paper or body.

on which the device is placed, with a yielding pressure. In the construction shown an arm 23 is pivoted to a lug 24 to swing in a vertical plane. A spring 25 is secured'to the block 20 at one end while its other end engages the arm to press it downward toward the paper. The arm carries a suitable marking device for engaging the paper. It may have a socket 26 into which a lead 27 may be inserted that can be clamped therein by a set screw 28 at one side of the socket.

The device is applicable to any form of a rule, by providing the'channel l3 and the rabbet portion 8 to fit the support, that is fixed thereto to have a snug fit yet to slide freely under the ruler.

The marking devices, of which three are shown, are adjusted along the slotted arm Patented Dec. 3%, Application filed February 18, 1909. Serial No. 478,569.

to form the lines the desired distance apart;

and the lead or other markers are adjusted therein to engage the paper by the desired pressure. Then upon holding the rule firm, and sliding the support and slotted arm along the rule, the markers will form as many parallel lines on the paper, and these lines will be parallel with the rule. Ob-

viously a greater or less. number-of markerscan be used and can be set at any desired distance along the'slotted arm. When not in use the device is readily detached by sliding it on from the rule.

Instead of a single marker 27, an arm 30 may have a double socket formed by a plate 31 secured to the socket ortion 32 by a screw 33. This socket mem r has two sockets 34 and 35 in which markers 36 and 37 may be clamped. The'sockets are inclined to bring the markers in close proximity whereby a double "line may be formed by one or more of "the markers.

Having thus described by invention, I claim:

1- The combination with a rule of a support slidable along the rule and having a transverse slotted arm, a plurality of 'marking devices each comprising a block having a tongue projecting into the slot of the arm whereby the block can be moved along the I ofthe block and extending transyersely to the slotted arm, said arm having means for carrying a marker, and a spring between the arm and the block for pressing the arm downward to cause the marker to engage the surface upon' which the rule is placed.

the arm, and aclamping member carried by,

the marking device having a pair of opposed walls, and means for pressing the walls together to. clamp a pair of markers therebetween.

3. The combirmtion with a rule, of a Support slidable along the rule and having a transverse slotted arm, a plurality of marking devices each comprising a block slidable along the arm, a clamping screw in each block arranged to clamp the block in adjuste'd positlons, an arm pivoted on the block and extending transversely to the slotted arm, said arm having means for carrying a marker, and a spring between the arni and theblock for pressing the arm downward to cause the marker to engage the surface upon which the ruleis placed.
